Answer 2

Answer:

see, there are both side is parallel

and the length of line between triangle is 12 cm

now, we divide triangle into two part

so, x

$x { = y + x }^{2} }^{2}$

x= square of 15- square of 12

x=225-144

x=81

x√81

x=9

we divide triangle into two part

so both part have equal hp

so value of x is 9×2=18
